SPECIFICATION forming part .of Letters Patent No. 723,705, dated March24, 1903.

' i Application tiled May 2l, 1902. Serial No. 108,398. (No modela Zo@ZZ whom, it may concern.-

Be it known that l, CLARA NNAN, a citizen of the United States, residingat Cape Porpoise, in the county of York and State of Maine, haveinvented new and useful .Improvements in Grates, ofwhich the followingis a specification.

My invention relates to new and usefnlimprovements in grates.; auditsobject is to employ a device'of this character havinga movable sectionwhereby apertures may Vbe formed within the grate of sufficient size topermit cinders and clinkers to be readily eX- pelled therethrough andinto the ash-pan.

Another object is to so construct the grate as to permit the entireVdevice to be 'shakenf /Vith the above and other objects in View theinvention consists in the novel construction and combination of partsVhereinafter described andV claimed, and illustrated in the accompanyingdrawings, showing the preferred form of my invention, and in Which-VVFigure 1 is a perspective View showing half of'the grate in positionwithin a stove. Fig.- 2 is a plan View showing the grate in positionWithin its supporting-frame. Fig. 3 is a section on line 3 3, Fig. 2.`Fig. 4t is a perspective l view of the bodyofithe grate detached. Fig.

5o in the back of the supporting-frame 1.

5 is a similar view-of` the sliding sectionrof said grate. Fig. 6 isavperspective view of a tool for operating said sliding section. Fig. 7is a detail View of the supporting-frame of the grate.

Referring to the gures by numerals of reference, 1 is a preferablyrectangular supportingframe adapted to be secured within a stove in anysuitable manner and having the front thereof cut away, as shown in Fig.7, the inwardly-turned ends? Vof said section being provided withhorizontal recesses 3 for thereception of the reduced ends 4 of ahorizontal strip 5. formed withtheforward ends of yarms 6, extendingfrorn a rectangular grate-section 7,' having pairs of parallel bars 8extending from front to rear thereof. Short arms or lugs 9 extendhorizontally from .the rear ends of the section 7- and projectinto andare adapted to slide within slots 10, formed with This V.strip issecured to or` ranged in parallel series and are so located as to lieabove Vthe spaces formed between the pai rsSofrthe movable section 7.The brackets 11 serve to prevent longitudinal movement of the sectionsof the grate independently of each other. Arms 14 .extend from oppositeends` of the body 13 and rest within grooves 15, formed within the upperfaces of the ends ot' supporting-frame l. One of these arms extendsbeyond the edge of frame l and terminates in an upwardly-bent hook 16,to which access may be obtained througha door in the stove or in anyother suitable manner. As the body 13 is shorter than the internallength offrame 1, a slight longitudinal movement of said body within theframe is permitted. ,Y

An arm 17 extends forward from the movablesection 7 and its cross-strip5' and also terminates in an upwardly-bent hook 18.-

This hook is adapted to be engaged by parallel ears 19, formed at oneend of a tool 20, and by means of lthis tool the arm 17, crosss'trip5,"and sliding section 7 may be drawn forward until the brackets 1lcontact with the front portion of body 13. Apertures will then be formedbetween `the series of bars 12 and the rear ends of body 13 and slidingsection 7, and through these apertures elinkers or other large objectsupon the grate may be shoved by means of`a poker or `other suitabledevice. After the parts havebeeu returned to normal position the ashesupon the grate may be shaken downward by placing the tool 2O inengagement with the end hook 16. The body 13 may then be moved back andforth from end to end, and as it cannot be moved independently of themovable section 7 said section will also be carried therewith. As thereduced ends et of cross strip 5 are shorter than the recesses3withinthe ends 2 and as the width of lugs 9 is -lessthan that of theslots 10, thereuwill,be'nothing to hinder this reciprocating motion ofthe movable section 7.

It will be seen that the device is extremely IDO simple in constructionand can be readi-ly operated and the parts can be quickly assembled ortaken apart, as desired.

In the foregoing description I have shown the preferred form ofmyinvention; but I do not limit myself thereto I am aware thatmodifications may be made therein without departing from the spirit orsacrificing any of the advantages thereof, and I therefore reserve theright to make all such changes as fairly fall Within the scope of myinvention.

Having thus fully described theinvention, what is claimed as new is 1.The (combination with a supportingi'rame open at the front, of a crossstrip loosely mounted in the open front portion of the said frame, agrate-section connected to said cross-strip and having lugs looselyengaging the back of the frame and provided with grate bars, agrate-bodysupported upon the frame and movable longitudinally thereon and having aseries of grate-bars therein arranged above the spaces between the barsof the gratesection connected to the crossstrip, and brackets on thelatter section engaging the bars of the grate-body.

2. The combination With the supporting frame havingan openingin'thefront thereof, of a cross-strip loosely mounted Within said opening, agrate-section connected to said cross-strip and having lugs looselyengaging the back part of the frame and also provided with bars, agrate-body mounted upon the said section and having oppositely-extendingarms engaging the frame, brackets secured to said section and engagingthe bars of the body, and means for moving the said gratesectionstransversely of the body, the latter being also movable.'

In testimony whereof I ai'iix my signature in presence of two Witnesses.

oLARA NUNAN.
